Respiratory symptoms are a common cause of distress in patients with advanced cancer. Optimal palliative therapy requires careful assessment and the appropriate use of symptomatic measures in conjunction with specific antitumor treatments. The etiology and management of the three major respiratory symptoms, dyspnea, cough and hemoptysis, are described. The indications for antitumor treatments and surgical procedures are briefly outlined, and symptomatic treatments, including drug and nondrug measures, are discussed in detail.

Pulmonary mucormycosis is relatively uncommon but an important opportunistic fungal infection in immunocompromised persons. The literature on the subject is sparse. We describe a recent case and review the literature to delineate the clinical characteristics of this infection. We searched the MEDLINE database for articles published in the English-language literature since 1970 and carefully analyzed 87 cases. The main risk factors were diabetes mellitus, hematologic cancers, renal insufficiency, and organ transplantation. Several patients had no apparent immune compromise. There was a predilection for involvement of the upper lobes. Air crescent signs on chest x-ray films were predictors of pulmonary hemorrhage and death from hemoptysis. Fiberoptic bronchoscopy was a useful diagnostic method, and histopathologic examination was more sensitive than fungal cultures. The overall survival rate was 44%. Patients treated with a combined medical-surgical approach had a better outcome than patients who did not undergo surgery. Thus, this relatively rare but often fatal disease should be suspected in immunocompromised patients who fail to respond to antibacterial therapy. Early recognition and aggressive management are warranted to maximize chances for cure. Optimal therapy requires systemic antifungal therapy, surgical resection, and, when possible, control of the patient's underlying disease.

Rhodococcus equi is a facultative intracellular, obligate aerobe, partially acid fast, gram-positive pathogen that causes cavitary pneumonia in animals and immunocompromised humans. We describe 8 cases of R. equi pneumonia in patients with advanced HIV infection (CD4 counts less than 100/mm3), 7 males and 1 female (mean age 30.8 years), observed between 1991 and 1994. A history of exposure to farm animals was found in 4 patients. The most common presenting symptoms were fever, malaise, dyspnea, cough and hemoptysis, chest pain and weight loss. Chest x-rays showed tipical focal area of consolidation throughout the lung (3 upper, 3 lower and 2 middle fields) associated with cavitation in 4 cases. The definitive diagnosis in our hands was delayed only in the first case in which conflicting data resulted from blood culture (Bacillus sp. isolation) and sputum examen (acid-fast bacterium in the Ziehl-Neelsen stain). Final microbiological diagnosis depended on blood cultures (n=5), bronchoalveolar lavage (n=1), sputum (n=1), lung biopsy (n=1). All the patients were treated with prolonged courses of antibiotic therapy (259 days, range 120-340 in 6 dead patients; more than one year and two months respectively in two patients alive). According to microbial susceptibility TMP/SMX, vancomycin, imipenem, rifampin, aminoglycosides, macrolides and quinolons were more frequently used. Resistant R. equi mutants were selected during therapy with TMP/SMX (n=2), rifampin (n=1) and erythromycin (n=1). Five patient underwent pulmonary lobectomy after exclusion of metastatic bacterial lesions. Only 2 patients are alive, one after 365 days of antibiotic therapy and upper lung lobectomy, one after 60 days of antibiotic therapy. Optimal antimicrobial therapy and the role of surgery remain, in our experience, uncertain.

Symptomatic endobronchial recurrence after treatment failure is common in advanced non-small cell lung cancer. Optimal palliation has yet to be defined. We examined the combination of near-simultaneous, high-dose-rate (HDR) brachytherapy with stenting in this cohort of patients. Informed consent for intervention was obtained for 10 patients experiencing severely symptomatic (hemoptysis and oxygen-dependent shortness of breath), biopsy-proven endobronchial recurrence. All patients (eight men, two women, aged 52-77 years) had failed to respond to chemoradiotherapy for stage IIIB non-small cell lung cancer. Intervention consisted of placement of a self-expanding metallic stent (Nitinol/Ultraflex stent, Boston Scientific Co., Natick, MA) into the obstructing region. During that same bronchoscopy, HDR catheters were introduced. A dose of 6 Gy at 0.5 cm from the catheter was then delivered via an HDR unit. Two additional HDR sessions followed at weekly intervals for a total dose of 18 Gy. Patients under went follow-up bronchoscopes 1 month after the last HDR and when clinically indicated. All patients completed the prescribed therapy. No morbidity was noted from bronchoscopy, HDR, or stenting. All patients had rapid relief of signs and symptoms. At 1 week after stenting/first HDR, a statistically significant improvement in Karnofsky status was noted. Pulmonary palliation was maintained for the duration of their survival. The radio-opaque stent also offered significant advantages for catheter placement and verification during the HDR procedure. Although this series is small, the beneficial outcome obtained deserves further evaluation.

Invasive pulmonary aspergillosis (IPA) is the most common fungal pulmonary infection in severely immunocompromised patients. Aspergillus species are commonly isolated from the soil, plant debris, and the indoor environment, including the hospital. Phagocytosis is the main host defense against Aspergillus conidia and hyphae. The diagnosis of IPA is based on clinical, radiological, and mycological data. Clinical signs have a low specificity. The most typical computed tomographic (CT) findings are nodules with or without the halo sign or the air crescent sign. Sensitivity of microscopy and culture of noninvasive collected samples is low. Galactomannan and nucleic acid detection in serum or in bronchoalveolar lavage (BAL) fluid help to confirm the diagnosis. Crude mortality is high and strongly correlated with the underlying condition, stage of the underlying disease, and extension of the aspergillosis. Optimal therapeutic strategies include the prevention of contamination in patients at high risk, early initiation of antifungal therapy, surgery in some instances, and, importantly, treatment of the underlying condition to restore whenever possible a certain degree of immunocompetence. Voriconazole has demonstrated better efficacy and safety than amphotericin B deoxycholate. The improved survival observed with voriconazole makes it a new reference for the first-line therapy of IA. Lipid formulations of amphotericin B, caspofungin, micafungin, and posaconazole are other therapeutic options in the event of failure of or contraindication to voriconazole. The main indication for surgery is prevention of severe hemoptysis when the lesion is adjacent to a large vessel.

Radiation therapy is an important and effective treatment modality when used in the management of oncologic emergencies. For any patient who has MSCC, ISCM, SVC syndrome, or life-threatening hemoptysis/obstruction, optimal management hinges on efficient multidisciplinary evaluation and communication to arrive at a treatment plan tailored to the individual patient. Optimal management may include steroids, surgery, chemotherapy, or bronchoscopic intervention. When radiation therapy is used, the total dose and fractionation schedule should be tailored to the disease setting and life expectancy of the patient.

Unilateral pulmonary artery agenesis (UPAA) is a rare congenital anomaly usually diagnosed in infancy due to associated cardiovascular malformations. We report a rare case of isolated right UPAA that presented atypically in adulthood with massive haemoptysis requiring a pneumonectomy. This case highlights the importance of maintaining a high clinical suspicion, the role of CT angiography and a multi disciplinary approach. Optimal management is often surgical however bronchial artery embolization (BAE) remains a useful adjunct.

Pulmonary sequestration is a rare and usually asymptomatic congenital anomaly. Optimal management of this condition is still a subject of debate, including superiority of surgical resection or angiographic embolization of the aberrant arterial vessel. Presently described is rare case of a 51-year-old male who presented with hemoptysis related to pulmonary sequestration associated with acute right lower quadrant abdominal pain caused by perforated appendicitis.

Cystic fibrosis (CF) is a multiorgan, genetic disease resulting from dysfunction of the CF transmembrane conductance regulator. The primary clinical manifestations are bronchiectasis, chronic pulmonary infections with recurrent exacerbations, and pancreatic insufficiency. Advances in CF care have led to improved survival, with more than one-half of those affected being adults. As a result, adult pulmonary and critical care physicians increasingly will be involved in the care of these patients. Patients with CF are at risk for numerous conditions that require ICU admission, including respiratory failure, massive hemoptysis, pneumothorax, hepatic failure, and bowel obstruction. Multiple aspects of the care of patients with CF benefit from specialized knowledge, including pancreatic enzyme replacement and nutritional support; airway clearance modalities; treatment of multiply resistant, polymicrobial infections, and unique drug metabolism. In extreme cases, patients may benefit from advanced therapies, including extracorporeal support and organ transplant. Optimal care of patients with CF requires a multidisciplinary care team that includes respiratory therapists, dieticians, social workers, psychologists, pharmacists, and physicians who have expertise in the treatment of this complex, multisystem disorder.
